My tomatoes are growing up into the lights.

Tomatoes grown in the AeroGarden must be pruned early and often in order for them to grow full and bushy, as well as to flower prolifically. If tomatoes are not pruned early enough in their growth, they will grow tall with lots of leaves and flowers at the top, but no growth on the lower stems. Once this has happened it will take some patience to train your tomatoes to leaf out again at the base.

Prune off about a third of the leaves (and flowers, if any are present) at the top of the plant, removing the newest, smallest leaves. This will stimulate the plant to branch out lower on the stem, and eventually to produce flowers and fruit throughout its height. You will need to continue to prune the top of the plant periodically until it fills out with even growth below.
